For the uninitiated, this is a tampon applicator. There used to be a new tampon in this, but there is no longer a tampon (of any kind) in it. As far as I can tell, anyway.

Per @glopdemon on Twitter: “Here’s a cool thing to find in the window of the bus.”

Indeed. You can apply a tampon and, however rudely, discard the applicator thusly, all while on Muni? I almost want to say, hats off, girl. This would be less interesting (and gross) if someone was simply playing with found tampons, but we can’t discount that possibility, can we?
